Learners explore the spherical protoplasts of plants. Students observe that plant cells have a plasma membrane in addition to the cell wall. Learners plasma membranes, solutes and organelles.

Students review the basic principles of plant cell structure, tissue culture, sterile technique, and cell transformation. Next students complete a plant transformation experiment using whole plant material in order to view evidence of...

Students explore the amount of lead in ceramic plates through an experiment. Students determine if everyday dishware is leaching lead into food. They chart their results and discuss how much lead in ceramic dishware may cause lead...

Pupils investigate DNA Fingerprinting techniques and applications. They participate in a scenario to analyze blood to discover who shattered a plexiglass backboards. In addition, they explain why the DNA fingerprint of blood from the...

Twelfth graders examine protein shapes through a computer program that can be downloaded off the Internet. The program allows students to see how proteins look when viewed with X-ray crystallography.

Learners explore the tissues of the bone. They discuss bone composition and physiology. Students perform experiments to compare and contrast the decalcifying properties of several liquids.

Students define biotechnology and discuss the economic impact of biotechnology. They also describe what a 1015 onion and a slow-softening tomato are and how they are produced. They examine the safety of genetically-engineered or altered...

In this grammar worksheet, students identify and locate vocabulary terms that all begin with the letter "E." There are 45 words beginning with "E" located in the word search.

In this earth science worksheet, students find the words that are related to the letter "E" and the answers are seen by clicking the link at the bottom of the page.

In this literacy instructional activity, students find the words that are in the word search puzzle that focus upon the vocabulary that is from the theme of the sheet.

In this matrix reactions worksheet, students fill in the blank about the process of glycolysis. Students also draw an organelle- mitochondrion and label the parts with the given names.

In this endocrine histology lab, students examine prepared slides of various glands/ organs. Students identify each slide according to the key given and research materials. Students draw or sketch what is seen next to the appropriate...

In this digestive system learning exercise, students answer a list of true/ false questions. The students answer questions based on their knowledge of each process of the digestive system.

In this replication of DNA worksheet, students match the correct definition of DNA replication to the terms given. Students also complete given statements with the correct term in the space provided.

Students examine diversity on the planet and the differences within a species.  In this investigative lesson plan students complete a lab that allows students to better understand the relatedness between plants. 

Students examine protein, what it is and how it functions in the body.  In this protein lesson plan students study the food pyramid, what a protein is and what it does. 

Students participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.

Students compare/constrast DNA sequence data for a portion of the rat GULO gene to the corresponding sequence in the inactive GULO gene in humans, chimpanzees, orangutans, and crab-eating macaques by identifying the shared sequences in...

Students discover that the answers to some of society's waste and clean-up problems may be no further than the soil beneath their feet. They perform a Gram stain on the colonies to determine some of their characteristics.

Enzymes create the conditions needed for biochemical reactions to happen fast. The general name that chemists use for a chemical entity that increases the speed of a reaction is a "catalyst." Enzymes are biological catalysts - they...

An article reviewing over enzymes and active sites.

This is a good page for explaining the development and function of enzymes. It includes links to help with the chemistry and the biology that comes up.

Investigate how enzymes facilitate chemical reactions that happen in the body with this tutorial.

Enzymes speed up chemical reactions by factors of at least a million. This project investigates some of the factors that affect how fast enzymatic reactions occur.
